Now that I've won a slam, I know something very few people on earth are permitted to know. A win doesn't feel as good as a loss feels bad, and the good feeling doesn't last long as the bad. Not even close.

This sport has given me so much that my hope would be to give back as much as I can for as long as I can.

I've been cheered by thousands, booed by thousands, but nothing feels as bad as the booing inside your own head during those ten minutes before you fall asleep.

Nothing can substitute for just plain hard work. I had to put in the time to get back. And it was a grind. It meant training and sweating every day. But I was completely committed to working out to prove to myself that I still could do it.

Life will throw everything but the kitchen sink in your path, and then it will throw the kitchen sink. It's your job to avoid the obstacles. If you let them stop you or distract you, you're not doing your job, and failing to do your job will cause regrets that paralyze you more than a bad back.

I play tennis for a living even though I hate tennis, hate it with a dark and secret passion and always have.

The great part about tennis is you can't run out the clock.... As long as we were still playing, I had a chance.
